The present invention relates to a detachable straw, and more particularly, to a detachable straw formed by simply assembling and disassembling two members having the same shape using a magnetic force.

An article includes a surface adapted for presence in an environment containing odoriferous nitrogen-containing compounds, a bonding agent, and bacilli bacteria. A method for binding bacilli to a surface is also disclosed. First, the surface is provided. The surface is then heated and placed under pressure. Then, the bacilli and a bonding agent may be applied to the surface, either alone or as a pre-mixed composition. The pre-mixed composition may be in the form of an aqueous dispersion. A method for controlling odors from odoriferous nitrogen-containing compounds is also disclosed. The method includes applying bacilli bacteria to a surface and placing the surface in an area likely to include odoriferous nitrogen-containing compounds.

In various embodiments, the present invention is directed to a drinking glass or cup that eliminated or substantially reduces contact between the user's lower lip and the rim of the glass or cup, thereby preventing or reducing lipstick marks and improving hygiene. In one or more embodiments, the drinking glass or cup of the present invention comprises a recessed or cutout portion sized to allow a lower lip of the user to enter the container when drinking.

Disclosed embodiments relate to containers, for example for holding food and/or beverages. In some embodiments, the container may have an outer body and an inner body. The outer body may define an interior space and have an opening leading from the exterior into the interior space. In some embodiments, the inner body may be configured to be provided concentrically within the interior space, and may include a cavity configured to retain food or beverage. In some embodiments, the inner body may be removably retained within the interior space of the outer body. Some embodiments may also include a cover configured to be detachably coupled to the inner body and the outer body, for example to close the opening of the container.

A stress-tight structure for forming a hollow tube includes a thin slice body having a first side edge and a second side edge. A deformation segment is formed on the second side edge and a tight engagement segment is extended outward from the deformation segment by a length. A first sharp projection is formed on an inside surface of the first side edge, and a second sharp projection formed on an outside surface of the second side edge and located between the deformation segment and the tight engagement segment. The second side edge is curled in a curling direction toward the first side edge to have the outside surface located at the second sharp projection of the second side edge correspond to the inside surface of the first side edge, and the first sharp projection is set in hooking engagement with the second sharp projection, thereby forming the hollow tube.
